/vt/ - Virtual Youtubers

I want to make a HoloLive-themed Pokemon ROMhack where instead of catching Pokemon, you catch idols (Think TouhouMon). Since there aren't 150 HoloPro members (yet) I thought that to fill out the Pokedex, I'd make each girl an evolutionary chain instead of a standalone mon but I'm having trouble coming up with evolved forms beyond that.
A good example of what I'm looking for would be what I've done with Kiara, where she starts as KFPEmployee (Fire) and evolves into Kiara (Fire-Flying) who can then become either Frog-Kiara (Fire-Water), Crow-Kiara (Fire-Dark), or Sheep-Kiara (Fire-Electric) depending on the conditions in which you level her up.
Additionally, since I couldn't think of any bug-type Holos (I'm not including the CN branch before you make that joke) I changed bug type to "Beast" type which includes Pekora, Botan, Polka, etc.
This project is very much in the brainstorming phase, so feel free to reply with any misc. suggestions you have. I want to start with a 'proof-of-concept' build that is basically just Fire Red but with the pokedex replaced before I do anything more ambitious.

tl;dr: What evolutionary forms could your Oshi have, and what types would they be?
